CONNECTION FOB LIQUIDFUEL BURNERS.

` application med July 22,

To all whom t may concern:

Be it known that I, GUSTAVE C.`LoRnNZ, a citizen of the United States, and a resident of the city of Milwaukee, in the county of Milwaukee, State of Wisconsin, have invented certain new and useful Improve ments in Connections for Liquid-Fuel Burn-k ers, of which the following is a specification.

The improvements relate to'means for connecting liquid hydrocarbon burners with the liquid fuel supply pipe, and have for their objects, among others, the provision of a strong and dependable connection which may be made and applied without unnecessary laboror expense, will meet all the requirements of use, may be quickly and easily adjusted to its proper position and to accommodate the parts which are connected thereby, and will provide at all times a secure and liquid-tight hollow connection between the said parts.

The improvements are illustrated in the accompanying drawings, in which Figure l is a plan of a portion of a wick troughor holder and fuel supply pipe,with a connection embodying the improvements mounted thereon and connecting them, Fig.-2 is a side elevation of the trough with the supply pipe, connection and a portion of the trough to which it is applied shown in vertical medial cross-section; Fig. 3 is an elevation of the supply pipe and connection and a fragment of the trough or holder; Fig. 4 is a detail ofthe ferrule or washer' forming a part of the connection.

The trough or holder l may be of any suitable size, and, as shown, is of usual form, consisting of concentric cylinders with an annular space between them adapted to receive a wick 2, and to hold liquid fuel llowing thereinto from the bottom inlet 3 for absorption by thel wick. It is also provided with inner and outer flanges 4 and 5 respectively, forming part of the burner.

The liquid fuel supply pipe 6 forms a connection between the reservoir and the burner, and may have as many burners as desired mounted thereon by means of the connections lthrough which the said burners com* municate with the oil supply.

The pipe clamp 7 is in the form of a saddle which lits the supply pipe 6 snugly, and is supported thereon, its lower extremities 7 being tapered and adapted to be turned around the pipe, so that when this is done 1921. Serial No. 486,713.

and the clamp is thoroughly soldered thereon a rigid and secure connection between the two is formed. A hollow nipple 8 extends upwardly from the saddle 7, and yits bore communicates with a hole 6 in the top of the supply pipe 6, which may be drilled after the saddle is mounted on the pipe. The upper end of the nipple enters the tubular exteriorally threaded lower extension 9 of the burner holding casting and is secured therein by means of the union nut 10, threaded on the exterior of this casting and engaging the ferrule 1l slidably mounted on thenipple, in such a manner that the said ferrule'is `tightly clamped between the nut and the lower edge of the extension`9.

This ferrule is preferably made of copper or some other relatively soft metal, is o-f annular form and has exterior bevels extending from its middle portion to its ends, bothV of whichr areinclined at an angle of substantially degrees to its horizontal axis. The lower edge 9 of the threaded tuf bular extension, which comes in contact with the upper bevel of the ferrule, and the inner portion of the lower edge 10 of the nut 10, which comes in contact with the lower bevel, are disposed substantiallyat an angle of 45 degrees and form seats for the said ferrule,- so that when the nut 10 is drawn up these seats will wedge tightly with the bevel and also compress it to a certain extent, thereby forming a secure and liquidtight connection., the ferrule tending to conform to the bevel of the seats and becoming tightly swedged to the nipple 8. In this manner an absolutely oil-tight and secure'connection is formed between the pipe clamp and the burner holder casting, at any point to which the latter may be adjusted vertically on the former, and an adjustment of the wick holder and oil trough 1 so kas to fix the level of oil therein at exactly the right height is provided for.

The upper portion of the burner holder casting is split lengthwise so as to form a curved saddle to receive the bottom of the trough ork wick holder 1, yto which it is soldered, and a central Abore, communicating with the bore of the nipple 8 is formed in the bottom of the saddle, so that a conduit from the supply pipe to the trough or holder l is provided;

ln assembling the parts the pipe clamp 7. may be secured to the supply pipe and the Specification of Letters Patent. Patented May 16, 1922. l

saddle l2 to the burner trough, in the manner described, and a conduit for liquid fuel then formedby drilling a hole through the bottom of the trough and the saddle 12 and through the top of the pipe, thus insuring a clean and perfect oil passage. If on testing the device after assembling, or at any time while it is in use, the oil level is found to be too high or too low, the burner may be adjusted vertically by loosening the nut l0, moving they burner casting up or down and then tightening the nut, without breaking the connection by distributing any of the n parts or interfering with other adjustments.

What I claim is:

1. A connection between 'the liquid fuel supply pipe and the burner of a liquid hydrocarbon stove, comprising a member secured to the supply pipeand having an upwardly extending tubular portion, a tubular member connected with and extending downwardly from the burner, and telescoping with the said upwardly extending portion, an annulus yof relatively soft material on one of said members, said annulus having beveled surfaces and adapted to act as a seal for the joint of the said telescoping members, one of the said members `also having abeveled portion in contact with Vthe said yannulus, therespective angles of the two beveled portions being different in degree.

2. A connection between the liquid fuel supply pipe and the burner of a liquid hydrocarbonv stove, comprising a member secured to the supply pipe and having an upwardly extending tubular portion, a tubular member connected with and extending downwardly from the burner, and telescoping with the-said upwardly extending portion, an annulus of relatively soft material on one of said members, said annulus having beveled surfaces and adapted to act as i a seal for the joint of the said telescoping members, one of the said members also having a beveled portion in contact with the said 4annulus, the respective angles of the two beveled portions being different in degrec, and a union nut threaded on the exterior of one of said members, projecting beyond it and having inwardly turned annular beveledportions on the projecting 4part adapted to be brought in contact with other beveled surfaces ofthe said annulus bythe rotation of the saidnut and to press against the said annulus and compress it, whereby the latteris swedged and caused to bind on the whereby all of the said parts are united and fixed in position.
